Plastometer PM-04

Plastometer PM-04

Measurement of plasticity of coal is performed according to procedures described in norm ASTM D 2639 - 90. During the test, a dependence of rotation of agitator, which is placed in a retort with a measured coal, on temperature is measured. During a measurement, the agitator is exposed to a constant torque, which is exerted in a propeller unit by a hysteresis brake. 

Tests are performed in a temperature range from 300 to 600 ˚C. To comply with the measurement procedure, it is necessary to follow all the steps defined in the norm ASTM D 2639 - 90.

The measurement is controlled automatically using an enclosed software.

This device is manufactured in cooperation with RMI Ltd., Lázně Bohdaneč, which is also the exclusive distributor.
